[vtkusers] how do I traverse a probe (a line) result to get thevalues?

[Nico Vermaas]

Hi

I am afraid that I get an error when I try that:
"no matching function call to 'vtkDataArray::GetValue(int &)'"

and is there a way to get the number of points in the probe? where you have put the '?' ?

for(i=0; i < ?; i++)
  Probe0->GetOutput()->GetPointData()->GetScalars()->GetValue(i)
